Basement insulation in a mixed-humid climate
1920s house in TN, heating-dominated climate. The house has a full basement, completely below-grade. The previous owner had 6″ batts installed in the basement ceiling, but no air sealing. Here’s my question: I’m going to remove the insulation so that I can Air Seal the entire area. Do I even need to reinstall the insulation after I’m done? It’s constantly 60-65 degrees down there, so it seems like conductive heat transfer would be minimum even without the insulation ( we keep the t-stat around 60 in the winter and 70 in the summer). I intend to insulate the rim joist after the air sealing is complete. Any thoughts would be appreciated.
